Southampton claimed all three points in injury time to secure a first Premier League win under boss Mauricio Pellegrino.

The Saints allowed a two goal lead to slip despite playing against 10 men for the majority of the clash after Marko Arnautovic received a straight red card for a deliberate elbow into the face of Saints defender Jack Stephens.

Manolo Gabbiadini opened the scoring for the hosts with just over 10 minutes played after connecting with Nathan Redmond’s delivery.

And Dusan Tadic doubled the Saints’ lead from the penalty spot following Jose Fonte’s needless pull on Steven Davis in the box.

Two poacher like goals from Javier Hernandez in the closing stages of either half looked to have rescued a point for the visitors before Pablo Zabaleta gave away a penalty in the dying seconds.

And despite Joe Hart’s best efforts to distract Charlie Austin, the Saints striker slotted home from the penalty spot to hand the hosts a morale boosting win.

Watford maintained their unbeaten start to the season with an impressive away victory at the Vitality Stadium.

Hornets boss Marco Silva failed to pick up a single away victory during his time with relegated Hull City, but goals from Richarlison and Etienne Capoue ensured the Portuguese boss shed that unwanted record.

The victory leaves Watford on four points from their opening two fixtures, while Bournemouth slumped to a consecutive defeat and have yet to score a goal this season.
